Garden Rooms are considered to be permitted development, not requiring an application for planning permission*, provided all the following conditions are met. At Hawksbeck we will work with you to make sure all the criteria is met;
Garden Rooms must be single storey with a maximum eaves height of 2.5 metres and maximum overall height of 4 metres with a dual pitched roof, or 3 metres in any other case.
If the Garden Rooms is within 2 metres of the property boundary the whole building should not exceed 2.5 metres in height.
You can go up to 50% of the area of all your garden.
The area of your garden is all your land except the part the house stands on, so the area includes the front garden, side gardens and back garden, less the area of any other buildings, fuel tanks etc.
No buildings are to go in front of the front elevation of the house
Conservation areas; you cannot build at the front or side, but you can place a garden room in the back garden
Listed buildings; need full planning permission.
Areas of Outstanding Natural Beauty; max size of 10sq metres at least 20 metres away from the house.
Any new building must not itself be separate, self-contained, living accommodation and must not have a microwave antenna.
*Should your garden room need planning permission (does not meet the above criteria), we can provide a full planning service for you. From design through to submitting a planning application
Investing in the right garden room not only makes sure you have a lifetime of use out of it, but also adds value to your house.
Estate Agents base their valuations on the total floor space of habitable accommodation within boundary of the plot. Because every Hawksbeck Garden Room comes with a building regulations certificate, it is therefore classed as habitable space.
In 2018 the average cost of property sold in Greater London was £5,131 per square metre. So if you were to build a 20sqm garden room, that would add £102,620 to the value of your house.
SIPs out-perform other building methods in virtually every thermal and structural category because the insulation is a component of the system, rather than an addition. As a consequence, they have exceptional thermal performance and u-values (drastically reducing your heating and energy bills) and making SIPs a truly environmentally friendly option.

Garden room costs can vary dramatically from supplier to supplier. The cost of a garden room can also depend on many factors such as:
Internal specifications such as electrics and plumbing adding, air conditioning etc.
Hawksbeck garden rooms are built to building regulation standards, which means our quality is far superior to many other standard garden room options. Our garden rooms are built with premium SIP’s panels, therefore allowing you to use your garden room all year round in every weather condition.

Our garden room quotations include foundations* and base, the cost of the actual garden room as well as all project management time.
*Foundations are subject to site survey and approval by our engineers and the building inspector.
Our average garden room build time is ten working days, however this will depend on any additional services you require. As we use structurally insulated panels for our garden rooms, the actual construction part of the garden room is relatively quick and easy.
For larger, more intricate garden room projects, that may involve plumbing in bathrooms or kitchens as well as electrics and media equipment, a bespoke timeline would be required.
Many clients choose to have their garden landscaped or paving added after the garden room has been constructed, which would also require extra time.
